Lenovo Ideapad 3 15IML05 NOT TRIGGER MB : GS452/GS552/GS752 NM-C781 Rev :1.0

Hi every one. Lenovo 3.3VALW and 5VALW are ok. When pushing on power button light comes after 15 seconds and remains always on but laptop not trigger and 1.8VALW, 1.05VALW are not coming.
Found a burned spot on LV5075B, fixed a newly purchased IC, but still 1.8VALW and 1.05VALW are failing though all conditions for their outputting existed (attached photo).
Also 1.05VALW and 1.8VALW outputs are checked not to be grounded.
If I didn't fix a new LV5075B, I would suspect the Ic. Is it possible for the new Ic to be defected then I have to fix a new one ?

Also, all conditions for EC IT8586E to help triggering exist but PBTN_OUT# measuring 2.44V remains fix when pushing power button and EC_RSMRST# is 0.1V ??
I flashed EC and Main spi with dumps from Lenovo site to no avail.
Do I have to search for another EC dump or rather fix a new IT8586E chip ?

Any suggestion to help fix the issues is welcome.

Has any member encountered similar issues ? P.S suggest any further diagnostic step to help fix the issues. Thank you;

Remove RC1108 and re-measure the voltage on PBTN_OUT# - if still 2,4V then replace IT8586E.

Thanks for your reply and sorry for my late reaction. I did cut the pad (represented in schematic by RC1108) and PBTN_OUT# remained unchanged i.e 2.4V . I have then to replace IT8586E and maybe later LV5075E if still not get 1.05VALW and +1.8VALW outputs.
